Century 21 had already produced very popular
toys from Thunderbirds and
Captain Scarlet and The Mysterons.
With Joe 90 they released two versions of Mac's Car,
a version of Sam Loover's Car, two different gun sets, a badge, and
Joe's case.

Possibly the rarest of the Century 21 toys is this battery
operated version of Mac's car. It looks almost identical to
the friction drive version and features:

Forward and reverse movement

Pre-set rear wheel steering

Hand operated tail fins

Automatic wing action

Real headlights

Powered by two "D" size 1.5V batteries and operated by a
walkie-talkie style control (not wireless) this marvellous toy
does exactly what it says on the box. It goes forwards and backwards,
opening and closing its wings, with its headlights on. Hours
of fun.

Non-lethal target practice for the kiddies with this tiny
gun. Includes a silencer, four sucker darts, and four targets
(a car, a rocket, a tank and an aeroplane).

I assume you couldn't use the silencer and the darts at the
same time, so the possibility of suckering someone to death
with any degree of stealth was negated. Still, plenty of opportunity
to torture the cat.

The ideal gift for any nine-year-old secret agent. With concealed
compartments that contain everything you need for dangerous
missions: a pistol, silencer & sucker darts (from the "Crackshot!"
game), a W.I.N. badge (similar to the one above, but smaller),
a W.I.N. transmitter water pistol, and a pair of electrode glasses.
